Taco SR502-2 Pump Switching Relay, 2 Zones, With Priority

Taco's pump switching relays is the ideal choice for all zoning needs. What makes this model unique is its ability to completely customize the system for your requirements, which is achieved by combining PC board layouts of the Taco zone valves, priority zoning circulators, thermostats and 00 circulators with the advanced features of the Taco zone controls. Troubleshooting the system is made easy, thanks to external diagnostic lights which show full functionality of the switching relay. Regardless of the application, Taco has products that optimize system performance while simplifying installation and servicing.
